To aZZ whom 'it-may oaf/wem Be it known that. we, WILLIAM l?. BRAUN and ALBERT BRAUN, citizens of the United States, residin at Brooklyn, inthe county of Kings and tate of New York, have invented certain new and useful improvements in Methods of Making Brushes, of which the following is a specification, reference being had therein to the accompanying dra-wing.

'lhis inventlon relates toa novel method for making brushes. f

rlhe primary object of the invention is to furnish an improved method for making a brush of simple and inexpensive construction which may be readily and expeditiously manufactured from stock material.

Another object of the invention is to furnish an improved method for inserting the bristles yinto the handle and.A for securely locking the bristles in position.

l Vf ith the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel method hereinafter described in detail, illustrated in 'the accompanying drawing and more particularly pointed out in the appended claims.4 .Referring to the drawing;

Figure 1 is a longitudinal sectional view of acomplete brush manufactured in accordance with our method. f

Figurev is a similar view showing the brush handle, bristles and fastenin means `prior to the linsertion of the brist es into the ferrule.

Figure 3' is a transverse sectional view taken on yline 3-3 of Fi re 2,

Figure 4. is a view similar to Figure 1, showing the position of the bristles after they lhave been forced part way into the ferrule. r

in the drawing, l designates a hollow 0r tubular brush handle provided at one end with an enlarged tubular portion`2. 3 designates suitable brush material such as bristles, qand 4 the means for forcing theVV bristles into the enlarged tubular portion and for locking the same within said'tubular portion. The member et consists pref-v erably of a single piece of wire which before thebrush is formed is fbent to provide opposite legs 5 connectedtogether by a cross head ora-loop 6. The legs 5 are inserted throughthe passage way 7 in the handle 1 until the loo-p 6 contacts-with the head 8 of the handle. At this time the extremities of the legs 5 project beyond the outer endv 9 I of the tubular portion 2 and a tuft of bristles or other brush material is placed on the end 9 between the legs. Subsequently the loop 6 and the extremities ofthe Ylegs 5, are twisted in opposite directions and this will cause the legs to be twisted within the' handle, as shown at 10, andwill also cause the twisted portion 11- above the bristles or other brushm'aterial to force said bristles or material intothe enlarged tubular p0rtionin. the manner indicated in Figure 4. rlhe twisting is continued until the. bristles or other brush material occupy the position shown by Figure 1, at which time the end portions'of the legs 5 are cut off at a point 12 and the ends 13 of the .bristles or other brush material are trimmed to provide a complete brush. v

. rlhe brush formed by this method; has bristles or other brush material which are securely locked in position, and it has been found in practice that these bristles or other material will remain in this position until the brush is worn out.

From the foreging, we believe that the y steps of the method, and advantages of the invention may bel readily understood by those skilled in the art, and we are aware that various changes may b e made in the method described, without departing fromthe spiritvof the invention as expressed :in

the claims;v f

What we claim and desireto secure 'by v through said "member, placing brush mate-v rial between said strands, and twistin said ,strands together to force'the materia 'v into said'tubular member. y

3. A method of manufacturing brushes consisting in providing a tubular member, inserting a plurality of strands of ,wire

through seid member, placing Brush ynrwubeour signatures in the presence of two witrial between said strands, twisting said nesses. strands together toforce the materiel into WILLIAM P BRAUN [L s] said tubular member, and cutting the end portions .of said strands after the brush ALBERT'BRAUN A [L SJ materiel has been Aforced into seid tubular Witnesses: v member. v 4 'HENRY BR'AN,
